1.	A pencil, when dipped in water in a glass tumbler, appears to be bent at the interface of air and water. Will the pencil appear to be bent to the same extent, if instead of water we use: liquids like, kerosene or turpentine? Support your answer with reason.
Answer» A pencil when dipped in water in a glass tumbler appears to be bent at the interface of air and water due to phenomenon of refraction of light. As we know, different materials have different refractive index. So, the amount of refraction for different media will be different. Hence, pencil will appear to be bent more or less depending on the refractive index of the medium.
